Purpose: the purpose of the present invention is to offer resin compositions which have antimicrobial/fungistatic properties which show outstanding dispersion and outstandingly durable performance. Constitution: thermoplastic resin compositions characterized in that an antimicrobial/fungistatic agent, and particularly an inorganic antimicrobial/fungistatic agent, is compounded with a copolymer containing a polyether chain as a constituent unit, such as a polyether/polyamide copolymer, a polyether/polyester copolymer or a polyether urethane, for example, at 0.05-20 wt.%, and thermoplastic resin compositions which comprise a thermoplastic resin, an antimicrobial/fungistatic agent and a copolymer having a polyether chain as a constituent unit.
Le but de l'invention est de proposer des compositions de résine ayant des propriétés antimicrobiennes/fongistatiques, ainsi que des performances remarquables en ce qui concerne la dispersion et la durabilité. Ces compositions sont caractérisées par le fait qu'un agent antimicrobien/fongistatique, notamment un agent antimicrobien/fongistatique inorganique, est associé à un copolymère dont l'unité constitutive est une chaîne polyéther, tel qu'un copolymère polyéther/polyamide, polyéther/polyester ou polyéther/uréthane, par exemple, à 0,05-20 % en poids. L'invention concerne des compositions de résine thermoplastique qui comprennent une résine thermoplastique, un agent antimicrobien/fongistatique et un copolymère dont l'unité constitutive est une chaîne polyéther.
